B84144B0400S121

Power Line Filter Modules Overview

The B84144B0400S121 is a three-phase (wye) EMC/EMI line filter module manufactured by EPCOS - TDK Electronics. It features a chassis mount configuration with terminal post termination. The rated AC voltage is 305 V relative to phase and 530 V relative to ground/neutrals at 50-60 Hz. The rated current is 400 A, referenced to a 40 °C ambient temperature. The unit provides three-stage filtering capability.

Power Line Filter Modules Feature Summary

• Three-stage electromagnetic interference suppression for three-phase power systems
• Chassis mount design with robust terminal post connections
• High current handling capacity suitable for industrial applications

Power Line Filter Modules Applications

• Industrial converter systems
• Three-phase power distribution networks
• EMC compliance in heavy machinery

Power Line Filter Modules Procurement Notes

Verify the specific suffix S121 against the official TDK/EPCOS datasheet to confirm terminal post orientation and mounting hole patterns. Ensure the application environment does not exceed the 40 °C reference temperature without derating considerations. Confirm that the 400 A rating aligns with the peak load requirements of the target installation.

Power Line Filter Modules Selection Notes

Select this component when a high-current, three-stage solution is required for three-phase wye-connected systems. Compare the 400 A rating against the maximum continuous load. Verify that the chassis mounting style fits the available enclosure space. Check if the 305 V/530 V voltage ratings match the network configuration.

Power Line Filter Modules Part Context

This part belongs to the B84144B series of power-line-filter modules from EPCOS - TDK Electronics. These filters are designed for industrial environments requiring significant noise attenuation. The series typically includes variants with different current ratings and mounting styles, such as the B84144B0600S120.

Power Line Filter Modules Replacement Considerations

The B84144B0600S121 is documented as a parameter-equivalent substitute. Verify mechanical dimensions and electrical ratings before swapping.
